BMW 320d E46 does not start EWS

[chiptuner8]

Hi guys!

I'm looking for help with this problem.

I have an BMW 320d E46 and does not start. Car stopped running in road and does not start again.

After diagnose it, these DTC faults are registered:

- 4A42: Interface Error EWS
- 4121: DDE Relay
- 4703: Control unit internal 7

I have readed DDE and EWS (Attached files)

I have checked DDE relay and is ok

I have bought a new EWS but I have not cloned it until I heard your advice.

I hope you can help me. Thank you!
